How Can I Solve for the Temperature of a Spiral Inductor in Comsol Multiphysics?

AI Thread Summary
To solve for the temperature of a spiral inductor in COMSOL Multiphysics, ensure that all material properties are correctly defined, especially for the inductor and the surrounding glass substrate. The issue of a singular matrix typically indicates a problem with the model setup, which may stem from improperly defined parameters or boundary conditions. It’s essential to select the appropriate solvers for heat transfer by conduction and conductive media DC. Users should verify their model's geometry and mesh settings to avoid common pitfalls. Proper configuration will facilitate accurate temperature calculations for the device under DC current conditions.

Hi, this is my first post.

I'm new in using comsol multiphysics and I'm trying to model a spiral inductor which is placed in an another material (glass) which is over a substrate. The pads of the inductor are outside the material. What I'm trying to find out is, the temperature of the surface of the device given given a dc current of the inductor. i don't know which solver to use working with heat transfer by conduction and conductive media dc.

I usually get a message of singular matrix.

Thanks in advance!

A singular matrix is often a sign that something wasn't defined properly in the model. Make sure that the properties of all elements are set properly for all the physics used.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
