ElmerGrid / MATC bug ?
for scripting I use MATC variables to define my grid size. I ran into a recent bug where I had an 8x8 grid that worked fine, but a 9x8 grid would crash elmergrid. (it wouldn't throw an error message. I'd get some sort of unhandled exception crash). Here's the working grid file: ***** ElmerGrid input...

Re: Saveline ordering error
ok, I'll give the multiple polyline a try. I see that the documentation mentions the points needing to be entered in pairs. DOes that mean that if I try adding more than two points to the polyline definition, it creates multiple two point line segments, rather than a single polyline with multiple po...

ElmerParam in Windows build?
I had read through the Elmerparam manual and was interested in trying out a few things. I quickly realized that Elmerparam appears to not be included in the default Windows build. is this correct or am I missing it. I searched for the interface libraries as well and didn't see those either. I was in...

Re: Saveline ordering error
Two more things: (1) I've noticed that despite the line File Append = Logical False some of the files are appending rather than overwriting if I rerun the simulation. Not sure if it's because of the multiple SaveLine calls, or what. the current sif file saves data in 5 different files, mainly becaus...

Re: Saveline ordering error
thanks for the quick reply. When I meant incorrect order, I wasn't referring to the column ordering (which yes, is reverse from what was stated in the solver text, but as you said is pretty easy to discern). I was referring to the first two rows, where position 0 is second on the list. Even if the c...

have a model where I'm pulling off the temperatures along two axis using the following solvers in the .sif: Solver 3 Equation = "SaveLine" Exec Solver = "after timestep" Procedure = File "SaveData" "SaveLine" Filename = "centerline.dat" File Append =...

Adaptive mesh, transient sim, elmerpost?
Doing a 2D transient simulation with phase change (enthalpy method). Runs fine without adaptive meshing. Turning on the adaptive meshing, it generates a bunch of RefinedMesh# folders (# from 0 to 9). When it's finished, there are .ep files in all of those folders plus the normal mesh&results fol...

Re:A Simple 1D temp mode
Not currently set up for recompiling. Will just do a 1 element wide 2d model. I forget, if i don't have any gradients in one direction, do i have to be concerned about high aspect ratio elements. Some materiel layers will be much thinner than others.

Simple 1D temp model
Setting up a 1 dimensional multi-material heat conduction model. Right now steady state. Have BC's set on either end. Runs fine if I specify a temperature on both ends, but if I specify a heat flux on one end with T=0 on the other, the model gives a: "SolveSystem: Solution trivially zero!"...
