Hi Markus,

Actually the hotCylinder test case is in the recently released solidMechanics solvers for OpenFOAM-1.6-ext (see here...

Sargam,

OK, I would recommend a thick walled cylinder with temperature T_i at the inner surface and T_o at the outer surface - described here...

Sargam,

Hmmnn I am not sure what boundary conditions are assumed in the analytical solution, it is not clear. The solution says the beam is clamped at the left and right and then says that the...

Hi Sargam,

OK from your log, your model is converged. By the way, you can see that the solver is doing zero inner iterations, this is because your linear solver tolerance needs to be tighter than...

Hi Sargam,

I notice that your model is only converged to a residual of 1.5e-5.
Normally I would converge my solid models to at least 1e-6. I recommend that you converge the model the a tighter...

Hi Sargam,

Yes, you need to set d2dt2Scheme to steadyState. But also the case needs to be converged - either by using enough outer correctors OR by using multiple time-steps.

Could you post...
