ConvergeCFD

converge, CONVERGE_Studio, tecplot_for_converge, post_convert etc are all supported on the HPCBOX platform.

Installation​

Converge is installed under /opt/drz/apps/convergecfd/<version>. ConvergeCFD provides its own preconfigured module files and environment scripts for different MPI variants. Application and MPI settings are placed in a modulefile under /opt/drz/apps/convergecfd. This modulefile can be used to set the location of the vendor provided modulefiles directory. Intel MPI settings can be overridden on compute nodes by placing MPI related environment variables in /etc/hpcbox/impi_settings.sh.

A sample ConvergeCFD module file can be found below.
