using the Optimization Module

Please login with a confirmed email address before reporting spam

Hi everyone

I am interested in using the optimization module. I have read its user manual and found the following points:

  • You can use the control variables directly to parameterize any aspect of the physics that is controlled by an expression. This applies to material properties, boundary conditions, loads, and sources. However, control variables cannot be used directly in the geometry description. Instead, the model must be set up using a Deformed Geometry or Moving Mesh interface to control the shape of the geometry. Then use control variables to control the mesh movement, effectively parameterizing the geometry.

  • The optimization module can be used for estimating modeling errors caused by uncertainties in material properties or for predicting the effect of a geometrical change.

Does this mean that the optimization module can be used for optimization of actual material properties of the material itself (not only material parameters), please?

Best regards, Manal

I am not sure what you mean by materiel properties. There might be some limitations for composites, but it it impossible to say whether this is relevant for you without more information. In topology optimization the Young's modulus is typically allowed to vary spatially.
