12. Apr. 2012 · In Linux, use a text editor to create a file named 'run.sh', and add the following two lines, save and close the file. elmergrid 1 2 step. elmersolver. Open a terminal window in the folder and enter 'run.sh', and it should run. The mode of the file 'run.sh' may need to be changed to 'executable'. Rich.
22. März 2011 · Elmer does have the mesh three bodies separate and selectable. One body is an air volume with "pockets" for thermal transfer fins of the second body which is stainless steel with the positive fins, and a flat rectangular surface opposite the side with the fins. The third body is PVC mated up to the flat surface of the second body, (this is a ...
24. Jan. 2019 · In this case the normal is automatically directed by Elmer to point outwards from the body containing the fluid. To get the same problem by using the keyword "Pressure i" one must define. External Pressure = 100001. External Pressure = 100000. The solution is essentially the same as obtained by using the original BCs.
Indeed it is, in the model the heat cannot leave by any other means. The problem is that the warm fluid leaving the system has more energy than that supplied via the heat flux BC, by 20% more in my linear tet model. In my 2nd post with the second order tets that wouldn't converge, it was the the fluid flow that would not converge,the heat ...
4. Sept. 2009 · I have noticed a change in the behaviour of the "Boundary Sum" of the SaveScalars solver. When doing. Code: Select all. Variable 2 = String "Stress Vector 1". Operator 2 = String "Boundary Sum". in SaveScalars solver for two boundaries (i.e. Save Scalars = Logical True in BC1 and BC3), I was getting two outputs, one sum for BC1 and one sum for ...
2. Jan. 2020 · Re: Heat Equation - BodyForce. by kevinarden » 02 Jan 2020, 22:07. Review the Elmer's Models Manual for more detailed information such as. Heat Source Real. A heat source h for the heat equation may be given with this keyword. Note that by default the. heating is given per unit mass, not unit volume.
18. Okt. 2011 · It took Elmer about 15minutes to finish each analysis using the following parameters in the solver: Solver. Optimize Bandwidth = True. Steady State Convergence Tolerance = 1.0e-7. Linear System Solver = Iterative. Linear System Max Iterations = 10000. Linear System Iterative Method = BiCGstabl. BiCGstabl polynomial degree = 3.
4. Juni 2013 · Hi. You need a third solver: the MeshUpdate solver that extends the displacement of the solid domain to the fluid domain. This also creates a variable "Mesh Velocity" which is used in the BCs in style. Code: Select all. Velocity 1 = Equals Mesh Velocity 1. Now there is at least the fsi_box* test cases that use this.
Simulate Solidification in Metals. by marcos1517 » 29 May 2013, 20:01. I'm new to Elmer, and i'd would like to use it as a tool for simulating the solidification process in metals. I understand there are two kinds of Phase Change models, which are Eulerian and Lagrangian. After reading some posts about this topic, i found that for Eulerian ...
