Plotting is a part of any project, because plots are essential to communicate your analysis set-up and results to others. In this article, we'll look at how to increase image quality and how to efficiently produce plots.
A number of enhancements have been made to improve the performance of the post-processor for cyclic symmetry models in ANSYS version 14.5. One of them is to display and animate results to only a fraction of the total model; consequently a fraction of the memory and computational expense is needed. Cyclic symmetry can for example be used on fan wheels and turbine blades, and is performed by dividing the model into N sectors, reducing the memory and computation time with 1/N when post-processing only a single sector. This can be a helpful tool when working on large models with small sector angels.
ANSYS 14.5 presents a new function that enables you to save your model in positions for post-processing purposes. The advantage is that you don’t need to be so careful when demonstrating your results since ANSYS now can memorize the perfect view for you. All you need to do is place your model in a desired position and save it.
Duplicating various conditions has been possible in previous editions of ANSYS. However, in ANSYS 14.5, this has been simplified where only a few steps are needed. This is a timesaving application where all the information regarding one item can be patterned onto multiple parts, maintaining all details. Not only does it apply to bolt pretension as will be demonstrated here, but to all loads, boundary conditions as well as mesh details.
Submodeling is a special feature in ANSYS 14.5 that previously was restricted to Mechanical APDL. The aim is to produce satisfactory results in a specific region where inaccurate results have been obtained. For instance, coarse mesh may not give sufficient accurate stress results. Therefore, by creating a submodel on the region of interest, new results may be achieved. In principal, the displacements calculated on the cut boundaries of the coarse model are mapped onto the submodel. Not only are more accurate results the benefit of this application, but also the possibility of experimenting with different designs for the region of interest. In addition, it helps you in demonstrating the dependency of mesh refinement. The mechanical application allows submodeling for structural (stress) and thermal analyses.
HPC is an abbreviation for high performance computing and introduces the concept of solving problems in parallel in order to reduce the simulation time. The computational power available to common users is rapidly evolving, giving the opportunities to solve complex simulations within reasonable time. Distribute the computational effort to several cores and thereby reduce the computational time significantly is a key advantage to quickly producing accurate results.
ANSYS Mechanical comes with many different licenses to choose from, and choosing the right one can be difficult. Therefore, a description of the most common licenses comes here:
If your engineering team is unable to set up a simulation problem and solve it simultaneously, you’re losing valuable time — time that could be spent beating competitors to market, engineering in new product features or addressing what-if questions. To support you in your efforts to reach greater productivity, ANSYS has developed a special cost-effective bundle.

Accessing a history of variables is not supported in CFX, but is a frequently desired feature. The answer is most often to create your own Fortran routine. There is, however, a nifty set of simplified routines that can be called from within CEL functions. One of these, GET_VAR, allows us to retrieve the time derivative of a variable.
Workbench has many useful functions which have not been utilized well. Update Project is one of them. According to its literal interpretation, Update Project intends to update all cells in the project that are in an update required state. It sounds quite plain and is ignored by a lot of Workbench users. In fact it is much more powerful than it looks like. With right settings, it helps us to do simulation in a smarter way. Here are detailed descriptions on some wonderful applications of it.
By using a parameterized geometry and mesh in Workbench a script can be used to re-mesh a geometry based on conditions set in CFX. In this simple example a rotor will deform the mesh until the value of orthogonally-based quality will trigger remeshing of the domain.
Turbulence is arguably the key element for the accuracy of computer simulation of any engineering flow. As complexity of flow physics increases, CFD must rise to meet growing demands for breadth of accurate and reliable turbulence models.
This Info Day aims to show how CFD simulation can meet your growing demands for accurately and efficiently capturing the effects of turbulence, and is held in Sweden, Denmark and Norway in October.

With the release of ANSYS Workbench 13.0 a new feature is presented: the “External Data” system which enables users to import data from external software/sources in text format into the Mechanical applications. The users can import an external file to describe temperatures, pressures, displacement (beta) or convection coefficients and apply it in a static structural, transient structural, steady state thermal, transient thermal or thermal-electric analysis. This article shows how to import and apply an external data file.
Microsoft Excel is probably the most popular calculation tool in engineering world. Therefore it is not strange that ANSYS Workbench can be connected to Excel. Even from early versions. The connection is strengthened in the latest release 13.0, and now Excel can be utilized in (at least) three different ways with Workbench: Export model information, Parametric study and Drive Workbench
This blog article is a summary of these three ways.

Many ANSYS Workbench users have asked on how to extract one model from a project which contains many simulations or how to duplicate a coupled anlaysis. ANSYS has provided solution for these challenges, although it is not so straight forward. This article presents the details on how to do so.

Many multiphase flows consist of two or more immiscible phases that are separated by distinct large-scale surfaces (e.g. free-surface flows), rather than being distributed in droplets or bubbles. Using VOF modeling, a single set of momentum equations is solved together with an equation for the volume fraction.
When using the pre/post and batch solver setup compared to using full licenses, some settings has to be done within ANSYS and maybe some changes in your working methodology. These settings and changes are described in this tutorial both for ANSYS Workbench and ANSYS Mechanical APDL.

Dynamic meshing refers to situations in which the computational grid changes dynamically during the run of the CFD simulation. This opens up for the possibility to simulate flows where the geometry changes with time, e.g. flows around falling objects or internal combustion in cylinders.
Being able to estimate the erosive wear on piping, valves, probes etc. is of great importance in many industries. Erosion analyses can be performed for internal and external flows. Examples of internal flows include flows in pipes, valves, flow meters, etc., and external flows include erosion on protruding details, e.g. measuring probes, screw nuts, flow around pipes, etc.
