[Nek5000-users] E INVALID BC FOUND in genfast

[nek5000-users at lists.mcs.anl.gov]

Hi Paul, 



I am also getting something similar, however it is referring to many elements with 

 a "BC fail" and then gives the E INVALID BC FOUND. I have attached the case 

and output log for referrence. 



I checked the elements that it is referring to and the BC's are good, so I'm not sure 

why it tells me this. I looked in fast3d.f and also couldn't figure out what "ierr and ierrmx" 

refer to. Could explain what this error means or what it is checking for? Thanks 

for any help!

Shriram, 

It's indicating that one of the bcs for element 3912 is not valid. 

What are those?
