Hello everybody,

I am solving a 2D square block case where temperature is changing only in y direction with zero displacement field at time=0. I am using pre calculated temperature values and fvScheme are not calculating for ddt scheme. My mesh is 100X100.

I have compiled elasticThermalSolidFoam solver for not calculation ddt scheme.

When I am running my case it is showing following problem:
Create time

Create mesh for time = 0

Reading field U

Patch bottomSurface Traction boundary field: U
Patch right Traction boundary field: U
max(detdd) = 2.75066e-32
min(detdd) = -1.11187e-48
average(detdd) = 2.32475e-33
max(detdd) = 2.75066e-32
min(detdd) = -6.84228e-49
average(detdd) = 2.33578e-33
nAddCells/nCells = 0.0198

Solving for U using GAMG, residual = 1

Does anyone have any idea why this problem is coming and how to fix it?

Thanks in advace.
