Batch processing through scripting appeared in CFD-VisCART v2006 and this feature kept improving since then. You can see a short description in this past user tip. This can be very useful to create meshes without graphical interaction or to set up similar models over and over.

The mesh has a great influence on the solver convergence and solution of every CFD Simulation. The user is strongly advised to check the quality of a numerical mesh.

Special approaches are needed when dealing with the modeling and analysis of various complex rotating systems having a stator and a rotor, in single or multistage, with change in the frame of reference from fixed to rotating (namely fans, pumps, compressors, turbines, propellers, impellers, diffusers, stators, vanes etc.).

While working with CFD-VIEW, the user has the option of saving an mdl file. This file stores all the entities created in CFD-VIEW, from the point the DTF file (or other data file) was imported, to their current state at the time of saving. The user can thus reopen this file anytime later to resume work.

ESI provides an Online Compiler on this website that can be used to compile user subroutines. To access this online compiler page, please click on the Compile Usersubs tab under User Menu on the left.

If you wish to use your own compiler, please make sure you are using the one listed in the table below for your platform.

Did you know you can output summaries, such as mass flow summary, force summary etc. at your desired time interval independently of the DTF file save frequency? This option not only saves time but also memory and disk space. Using a “Special DTF Update” command, you can activate the summary output frequency at your choice of iteration interval (for steady state cases) or time steps (for transient cases).
