I am repeatedly encountering a parsing error, seems to be related to my ini file but the ini file doesn’t seem to have any problems. because I couldn’t upload files I am attaching the text of the error message and the ini file here: Edit: the issue was fixed when I replaced w=0.0 with w=0 ```ini [backend] precision = double rank-allocator = linear [backend-openmp] ;cblas = Enter path to local

Without running the ini file myself, I think the error is from your number formatting, I don’t think your use of standard form is correct. Also, on a different note you might want to consider normalising your pressure terms, you will be burning a few digits in accuracy with large values like the ones you have. This is ---

Thanks a lot for your answer Will. The issue was fixed when I replaced w= 0.0 with w=0 the rest of the numbers were left in standard form thank you for your other reccomendation as well, I will definetly scale the pressure if it will improve the accuracy
