For simple cases, you can use Elmergrid as mesher also. And there is a postprocessing tool called ElmerPost (which includes a GUI, however, and is not actively maintained any more). So in principle you can do everything with the Elmer suite.

I have been investigating Elmer. In fact, acknowledging that I'm an idiot, I have been trying to learn a bit about these different pieces of software that may be utilized as components of larger multi-physics packages. And a larger physics package might be what I require, mostly to handle the shortcomings of my own software I am developing. I have not even settled on software to display the geometry of something. My program outputs logical predicates that define geometry. Those can be translated into whatever language a GUI CAD module requires. In a perfect world, performing operations like meshing and FEM and CFD could also be sent to the same suite in that same language. I am willing to sacrifice a bit of functionality if I can appeal to one single package (suite) just to keep my project as simple as possible. -TSodd On Mon, Jan 9, 2017 at 8:17 AM, Zenker, Dr. Matthias <[email protected]<mailto:[email protected]>> wrote: Hi Todd, did you have a look at Elmer (www.csc.fi/elmer<https://urldefense.proofpoint.com/v2/url?u=http-3A__www.csc.fi_elmer&d=DQMFaQ&c=7vND7vRFB1FzfxRXc-X80O-MJSZd5Q-IVyyYW-Ff2gY&r=3enlI3TuQDmO9BnMCnxq2Mfm4tAO6Z3_Ae1Yc57DMr4&m=DiSHKNUMY7R072g1lz93SR0ZrwMpeJSv87Bl6jzfG40&s=UQ8K4UXv5BRVhaoluNSAbJhv1qpYHWUk50feTdyFATo&e=>) as FEM engine? It can be operated entirely from the command line. You have to provide a mesh file (e.g. in gmsh .msh format). There is a commandline tool (Elmergrid) to convert it to Elmer’s own mesh format. You then have to write a configuration file for the multiphysics solver (Elmersolver) which again can be started from the command line. It writes an output file for postprocessing. Is that what you are looking for? HTH, Matthias Von: Todd Pierce [mailto:toddcpierce@gmail<mailto:toddcpierce@gmail>.com] Gesendet: Donnerstag, 5. Januar 2017 18:12 An: [email protected]<mailto:[email protected]> Betreff: [Gmsh] Command-Line Multi-Physics package? Crew, I know this is a bit ambitious, but I'm looking for a multi-physics package that can be almost entirely operated from the command line. I am developing a natural language processor (SBCL Lisp on Linux) and one of the output options is planned to be to be some kind of multi-physics program, with a CAD interface, FEM (presumably entails meshing) and CFD capabilities, perhaps others, if you have any ideas. In a perfect world, my program could output directly to the CAD module in real time, maybe send solving commands in real time too. That is a bit lofty, but I'm looking for ideas here. The OneLab server might do it, but I've been advised against by this mailing list before as being too involved. Since STEP format seems to be more standard that Gmsh, perhaps software that reads STEP might be appropriate anyway. This still leaves the question open if something can accept those commands in real time, not to mention sending commands to a solver in real time. I am early in the development of this project, which by the way, is a hobby, not a professional obligation I have. I am open to any other interesting possibilities for a natural language processor to be involved with multi-physics (molecular dynamics? Electronic circuit simulations?) Let's have fun here; the lives of airline passengers do not depend on this. -Todd ________________________________ Erbe Elektromedizin GmbH Firmensitz: 72072 Tuebingen Geschaeftsfuehrer: Christian O.
