AI Thread Summary
To model a transient heat flow in COMSOL for a plasterboard subjected to a short Dirac pulse, it's essential to ensure that a transient analysis is selected. Users should explore the appropriate menus in COMSOL to input time-dependent functions for heat flow. Tutorials available within COMSOL can provide guidance on similar problems. Engaging with the COMSOL Community Discussion Forum may yield quicker responses and additional insights. Proper setup of the transient analysis is crucial for accurately simulating the heat wave propagation.

Hello,
I wish to model with Comsol a simple situation: a plasterboard undergoes locally with one 3 ms duration a very short flash (Dirac) and I would like to see the evolution during the time of the wave of heat through volume.
The problem it is that I do not know how to enter a function describing during time the flow received by my field.
In which menu of Comsol is necessary it to go?
Help me because it is very important.
Thank you.

It sounds like a relatively simple transient thermal analysis. Are you sure you're using a transient analysis in Comsol? Comsol has several tutorials that deal with this kind of problem...

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 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

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...
