Kaleem -- please use a subject for your email that indicates the concrete
question you have.
The following error shown in step-49 during make run.
Exception on processing:
An error occurred in line <1430> of file
in function
void dealii::GridIn::read_msh(std::istream&) [with int dim
= 2; int spacedim = 2; std::istream = std::basic_istream]
The violated condition was:
in
Additional information:
Yes, thanks for reporting this. It's a bug in the library :-(
The problem is that two files that should be in this directory are not, in
fact. If you take the two files attached to this email, and put them into the
step-49/ directory, everything should work!
Best
W.
