help!!!problem in openfoam running process

heheda · July 3, 2020, 10:43

when i run the solver ,it jump that
'FOAM FATAl ERROR:
attempt to cast type wall to type lduinterface

from function refcast<to>(from$)
in file .........'

is the problem in 0/boundary ?or blockMesh?
because i used 'fluent3DMeshToFoam',there is no 'blockMesh'file in '0',who can help me please explicitly？

i assume that you created the mesh with fluent.
so after executing 'fluent3DMeshToFoam' you can
find your mesh in const/polyMesh.

please open the 'boundary'-file in this directory and
compare it with your patches in the 0-directory.

if you don't see anything strange and can't find the problem,
you should upload those files here, so i can check them too.

thank you very much.i have solve it.but another problem jumped out.can you help me again ?

i assume that the solver still works despite this warning message, right?
or does it stop?

obviously, there are upper and lower temperature-limits set for this EOS.
so, this message tells you that there is a temperature of 5660 K which exceeds the upper limit (5000 K) of this model.
