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 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

Thread 'Where is my curb stop?'

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
