Gaussian heat pulse at random points on surface

Please login with a confirmed email address before reporting spam

Hi,

I need to know how to select random points in 2D space on surface and apply the gaussian heat flux after every time step. Can anyone please guide me with this.

Best regards Shahid Ali

Hello Shahid,

The following blog posts should be helpful:

1/ on applying gaussian heat profiles: see this blog post

2/ on creating a randomized geometry using model methods (You may want to use this approach to randomly distribute patches on which the Gaussian distributions apply): see this other blog post

Best regards,

Jeff

Hi

Thankyou Jeff, I've seen these blogs they're quite helpful tho but they are about creating a random geaometrt. Is there any possibility to link a randomized function from MATLAB that it can operate the position of heat flux on the surface.

Thankyou Shahid Ali
