Hi,
I am trying to model a simple 2D transient heat transfer problem. For this I move a sphere with a constant boundary temperature trough a plane making use of the Deformed Mesh and the Heat Transfer in Solids Interfaces. But what I can not understand is...
1. Is it possible to move the sphere through the plane, if the both are solid (... does FEM allowed this motion)?
2. How does Comsol calculate the temperature in the empty space/overlap area between the time steps? Diffusion? (see attachment!)
best regards,
Antoni Artinov
use this forum cfd.online it may be helpful for your topic. good luck.
To the second question: I do not think there will be any heat transfer in a space not filled with a material. You will need to mesh the space around the sphere to get the heat condcution and convection. Maybe you can add radiation without meshing the "empty" space.
Kinda interested in this problem. How can a solid object move in solid domain (medium?)?
