Hi Eric, First, thanks a lot for your prompt response, I really appreciate it Initially I was very happy to see it running, then I found it was not done yet...! (learning to be more patient...) Yes, I just exactly did the same thing that you mentioned. I ran the exact same case with OpenFOAMv1811 (few changes here and there due to the differences between the versions but nothing meaningful was different). It ran perfectly fine with OpenFOAMv1811 so there should be something which needs attention in RapidCFD... Thanks, MJ |

Hi, MJ,
That's good that you tested your case with OpenFOAM-v1812. It is highly likely that the same case will run with OpenFOAM v2.3.1, but if you have the ability to test with OpenFOAM v2.3.1, you can test the closest version of OpenFOAM to RapidCFD. Nonetheless, your OpenFOAM v1812 test probably rules out the grid, for example, as the root cause. From there, you could start deconstructing your case to figure out where the issue is. Examples: - Will your case run with a constant wall T instead of the mapped T boundary condition? - Is it feasible to run your case with fixed density (you're modeling water, considering rho is ~1000 kg/m3 and it seems to vary with temperature)? Or... with laminar flow ? In other words, I recommend changing parameters until you figure out exactly what is causing the errors. Offhand, I am not sure what the problem could be, in part because you are using some features I never tested with RapidCFD (e.g., mapped T BC and possibly more). Another option is to take a known working OpenFOAM tutorial for chtMultiRegionFoam and getting that to work with RapidCFD. I wish you good luck with the troubleshooting process. Best regards, Eric |

Hi Eric, Thank you very much for your valuable input. Since I already had OpenFOAMv1812 on my system, I quickly used it to check if it runs there just fine. But I am in the process of getting v2.3.1 for a more meaningful comparison I will follow your input to get to the bottom of this... Thanks again and happy holidays Regards, MJ |

Hello,
RapidCFD installation steps have been documented at https://github.com/Atizar/RapidCFD-dev/issues/93. Also, some recent experiences with newer versions of CUDA are posted at https://github.com/Atizar/RapidCFD-dev/issues/92. Hope this helps. Best regards, Eric |
