Hi Everyone

I am trying to simulate a multicomponent mixture chemistry / transport using dieselFoam.

But I get the following error. Can someone help me find out what this is due to?

Thanks,




Create time

Create mesh for time = 0

I guess I had this once when my chemkin file was not properly formatted.
I had to change it a bit and then it worked fine.
