Using multiple POSDAT.F - simple trick


There may be instances when the simulation may require multiple versions of POSDAT.F to be used. For example, one POSDAT.F may be used to calcualte and another used to print. Everytime copy pasting the code or renaming the files as POSDAT.F may be a little boring / inefficient. In stead the following procedure can be adopted:

Suppose you have posdat1.f and posdat2.f for 2 different purposes. Rename them as POSDAT1.TXT and POSDAT2.TXT. Ensure that these files contain only the code that you write. The star generated code must not find a place here. and keep them int he ufile folder. In the original 'empty' POSDAT.F generated by STAR, use the follwoing line:


if you need to run the first job. this command automatically transfers the control to the POSDAT1.TXT. Mind that though they are named .txt they still need to be in proper fortran format. else, this will result in compilation error.

Also they cannot have the extension '.f' because star tries to compile them as separate files and ends up giving an error.

Question 2

Answer 2


How can I try STAR-CCM+?

You can download a free version of STAR-CCM+ from the CD-Adapco website

This version is limited to 16,000 cells per CPU across a maximum of 2 CPU's and allows full usage up to this limit.

You can import ngeom and ccm files (native CDA formats) as well as grd, cas and msh grids.
