To know the efficiency of the mesh size, how can we plot the error vs no. of elements/mesh size in COMSOL
Hello, I want to make stable oil based ferrofluid from MnZn ferrite nanoparticles prepared via hydrothermal synthesis. I tried to coat it using NH4OH+Oleic acid and then added acid so as to remove...
