Has anyone successfully implemented a structural topology optimization using level set method in COMSOL Multiphysics? I believe it will require a combination of Level Set + Solid Mechanics + Optimization + Moving mesh interfaces.
When running post-processing python script only one thread of the computer is being utilized. How to use multiple threads for computations? Basically, I am extracting displacements from all nodal...

I am a little confuse with the mechanism of solid lipid nanoparticles (SLNs). The main point of encapsulating drugs into SLNs is because some drugs have low solubility in water. Therefore, SLNs...
