Elmer Discussion Forum

Makes sense, thanks for the insight!

Hi, I would like to setup a study with the HelmholtzBEM solver. The problem would look similar to the AcouSTO Engines' shielding effect tutorial (page 20): I have a source in the middle of a domain and I am interested in the pressure on a sphere around it. For example, I might have a 2D disk (but I ...

Hi all!

PML are often employed when modelling an infinite domain, as in this COMSOL example. As far as I am aware, Elmer currently does not have a PML implementation. My question is: is the implementation of PML for the current acoustic solvers possible within the Elmer framework?

It works, thanks!

Hi! Fantastic news! The link above seems broken though (404 page not found)...

Thank you very much, that clarifies things.

Hi, quick question but I did not find an obvious answer to it yet. I used the `Element = "p:2"` keyword in the `Solver` section of one of my simulations using the `HelmholtzSolve` solver: Solver 1 Equation = Helmholtz Equation Procedure = "HelmholtzSolve" "HelmholtzSolver&qu...

Tested both of "vtu: Eigen Analysis = Logical True" and "Element = p:2". They work like a charm, and p:2 boost the accuracy a lot. Good stuff.

Hi Peter,

Thank you, that clarifies.

Cheers!

Hi Guys, I have seen that many solvers offer the possibility of specifying the type and order of the basis function through the Element keyword. As far as I understand, specifying Element = "p:2" will increase the element order from linear to quadratic for all solvers that support p-elemen...
