Re: Raspberry Pi Cluster - could it run openEMS?

I've made compiling the (accelerated) sse code conditional. The resulting source compiles and runs openems on raspberry. However, the resulting binary is very limited in features. The included patch is more like a list of items that need looking at to get a functional openems on arm. ---------------...

Re: Raspberry Pi Cluster - could it run openEMS?

I would put the -mfpu-neon in the CMakefile of openems: diff -c openEMS/openEMS/CMakeLists.txt.orig openEMS/openEMS/CMakeLists.txt *** openEMS/openEMS/CMakeLists.txt.orig 2019-10-18 09:40:04.320275767 +0100 --- openEMS/openEMS/CMakeLists.txt 2019-10-18 09:45:48.475160390 +0100 *************** *** 14...

Re: Using FPGA to accelerate OpenEMS core

Floating point is hard on FPGAs.

Parallella is a small board, with 16 floating point cores and an Arm running Linux. See this video:

Perhaps it would be easier to port openEMS to something like that.

Hyperlynx import update

I'd like to keep you informed on progress on hyp2mat, the tool to import pcb's from your cad system to openEMS. New features: - pdf export. - simplifying the model. Layers and nets can be selected; the model can be cropped in x, y and z. Attached a small example: importing an Arduino nano twice: onc...

Re: Release Notes on openEMS v0.0.30

Hi. I'm koen, and I'd like to introduce hyp2mat, a package to import printed circuit boards in openEMS. When you're designing a printed circuit board, there are moments when you want to simulate the board itself. Not the components; the board. Moments when you want to know: if I put a clean signal a...

Re: Replacement for SmoothMeshLines

Anyway, your scripts are running, now. Nice simulation, maybee you can send me a few informations about your underlying problem and your simulation results? Thank you. Works fine now. I'm interested in calculating the parasitic capacitance and inductance of a via in a pcb. This is useful if a micro...

Re: Replacement for SmoothMeshLines

Florian. I like the idea of generating a mesh recursively.Good. Could you try to run the accompanying m-file "genmesh.m" ? The m-file works OK with SmoothMeshLines. If I use the mex version of openEMS_generateMesh, I get one error: an empty result for mesh_z. If I use the matlab version, I get anoth...
