What softwares can be used for Thermal Analysis other than ansys and comsol. The software should provide solutions to methods, including conduction, convection, radiation, and changes of phase.
There are several simulation programs you can use to simulate the magnetic nanoparticles movement in a fluid such as Comsol and Ansys fluent. I think Comsol is the easiest one and is more convenient. However, i prefer to work by Ansys fluent software which is better and more comprehensive. Its worth noting that you need UDF code in Ansys fluent if you want to simulate the magnetic nanofluid behavior under the influence of an external magnetic field.
