Dear libMesh team,
Consider the following lines:
TransientLinearImplicitSystem& tempSystem =
equation_systems.add_system<TransientLinearImplicitSystem>("Temperature");
equation_systems.get_system<TransientLinearImplicitSystem>("Temperature");
That should work, shouldn't it? It actually works in a test code.
However, in my application, it gives:
ERROR: cannot convert system "Temperature" to requested type!

terminate called after throwing an instance of 'libMesh::LogicError'
what(): Error in libMesh internal logic
which means that the dynamic_cast fails. I can't find what is
different in my application from the test code. I should mention that
this problem only occurs for transient systems. Everything works well
e.g. for LinearImplicitSystem. Also, the problem occurs only on my
local desktop computer, not on the cluster. (Actually I only noticed
this problem because I ran my application locally to track down a
different bug...)
Okay, one more thought: is it possible your local compiler flags have
RTTI disabled?
