I have one question, the units of GMSH are meters? Because I am trying to generate the mesh of my project (Imported of SolidWorks) but doesn´t works, syas Rutine Error!

Thanks

As said here : https://forum2.spis.org/t/archive-What-are-the-units-of-length-in-GMSH-

there are no units predefined in gmsh. Generally, one would use SI units to define plasma parameters and thus use meters for the geometry definition.

Yes, Benoit, units are irrelevant to gmsh but not to SPIS and in particular SPIS-UI, which uses SI units.

=> you must use meters

Ok, thanks for your answers, I enlarge the resolution and this work, so for example if I define one point (1,0,0,0.1) and other point (-1,0,0,0.1) this have 2 meters in GMSH?.

Hi, the cuestion now is, can I change the units to milimeters? because I have my model in this units. I saw in global parameters setting some options but I don´t know if I can change.

Thanks for your time!!

Hi,

I just asked Julien, another SPIS guru, about this units question…

In fact, the numerical kernel of SPIS only deals with international units, i.e. meters… So the only possibility you have is to model your CAD in meters.

But if you feel like coding, you can as well create a script that scales your milimeter CAD to a meter one
