hi,
Does comsol allow us to enter material properties manually such as young's modulus and poisson's ratio??...because i assigned polyurethane material to a domain of my model but it showing red mark for young's modulus n poisson ratio on the list

Hi
you can enter material properties as "user defined under the physics, but the most "normal" way is to set material properties under "Materials" one per domein (or groups of domains) and there you can use predefined ones, or fully user defined or any combination, including changing some or all of the predefined ones you load in. There is no real limitation. If you have red marks, it could indicate that the predefined material properties are missing some values that are required for the "physics" to solve correctly

Good luck
