Hi Philip,

Small questions, I noticed that in writeFields.H of the elasticNonLinTLSolidFoam solver the density is updated with rho = rho / J.
I was wondering whether this is correct, since it is...

Hi Philip,

Thanks for all your help. I was wondering if it is possible to split up the time integration of DU into two steps. So first to solve for the velocity DV, and thereafter for the...

Hi,

Thanks for your quick response. Since the first order and second order scheme are giving me the exact same response, I looked at the source.

This is the code in backwardD2dt2Scheme.C:

Hi Philip,

I'm currently testing foam extend 3.0. When running the CSM test of the cylinder flap benchmark with the elasticNonLinULSolidFoam solver, the correct solution is found. However, both...

Thanks. I was thinking that it was caused by the time integration scheme. Unfortunately, backward differencing d2dt scheme is not implemented in OpenFOAM.

Hi Philip,

I've calculated the first 4 seconds of the CSM3 cylinder flap benchmark, and it seems that the displacement of the flap is growing over time. I've attached a plot of the displacement...

Hi Philip,

Thanks for your quick response. This fix seems to have solved the problem. At first I also tried to add the gravity force at each time step before trying the elasticGravitySolidFoam...

Hi,

I've modified the settings of the test case to run the FSI2 case. However, after some simulation time the solver stops, and when I look into the mesh there is a large overlap at the tip of...
