[aspect-devel] Problems running Aspect

[Timo Heister]

Hi Ian,

(cc'ing to the mailing list)

A couple of questions:
1. can you double check that you are using Trilinos 10.4.2?
2. Also, did you make any changes to the .prm (say box.prm)?
3. On how many processors are you running?
4. can you send us the program output please?

Thanks,
Timo
