I am currently trying to use a high performance computing system to run some aerodynamic simulations of a rocket, but I&#8217;m running into some inconsistensies between the solutions that my PC gives compared to the solutions the HPC system gives.

Both systems run almost the same version of ANSYS &#8211; 2023R1 &#8211; however, my PC runs on Windows 10 and the HPC system runs on Linux.<\/p>\n<p>My question is: has anyone ever encountered differences this wild in solutions between different OS&#8217;s? It seems very strange to me that this would occur.
