Hi,

Yes, i try something like this :

Code: Select all

Variable Coordinate 1, Coordinate 2, Time;  Real  MATC "if (tx(0)==0.4375&tx(1)==-0.15&tx(2)<=0.00005)sin(2*pi*20000*tx(2));else 0;"
but it's doesn't work and double loop generate a error.

Hi Fouzi

I would strongly encourage to write a small Fortran sniplet rather than trying to make complex expressions with MATC. It is much easier to debug proper code.

Hi peter,

Ok thank you, I have an other question please, do you know how in Gmsh can i check if there is a material inside the elastic plat box.

Hi,

under tools->options there is a visibility tab for both geometry and mesh.

HTH,

Hi,
Which one please, im looking for if it's A hollow or not,because may be the propagation not happen because there is no material inside the elastic plate, i want to know please whent i creat a surface and do translate==> extrude surface is it ful or hollow by default?


Thank you,

Fouzi

Hi, if you're still using the plate solver note that it only makes sense for 2D meshes. -Peter

Hi,

Yes Peter i am using the same solver,and i make 3D meshes, is it false?.

You can find out if there is a volume in your geometry by using the corresponding items in the "geometry" tab. You can find out if there is a volumetric mesh by using the corresponding items in the "mesh" tab.
I have never used "extrude", so I cannot tell for your 2nd question.

Yes. It does not make any sense to use plate solver for 3D solids. -Peter
