Question

So I am trying to solve the heat conduction equation on an annular cylinder made out of zircaloy-2. I have in SI units the various parameters required, such as specific heat, density, thermal expansion coefficient and thermal conductivity. However, my mesh dimensions are in centimeters and not meters, so should i change all my parameters in CGS units or should i just convert the length part, or is there something else i should do

Hello
You can use a transformMeshGenerator to scale your mesh back to meters

Use the FileMeshGenerator to read your original mesh and set it as the input to the transformMeshGenerator

Hey
What I meant was that my mesh is a annular pipe which needs to be in centimeters (like 7.5cm inner radius and 10cm outer radius).
So do i need to modify the values of the constants like converting them or something like that

You need to be consistent between the mesh units and the units in use in the simulation
Either scale the mesh or scale the constants.
