Re: About how-to set surface tension in Level Set Method

"ELMERSOLVER_STARTINFO.txt" windows wants to add a suffix to every file, but depending on options does not always show the suffix. This file name has no suffix, but it is a text file. If your suffix display option is off you will not see that it has a suffix, which it should no have one.

Re: About how-to set surface tension in Level Set Method

ELMERSOLVER_STARTINFO is a text file that contains the name of the sif file to be run

It isn't required to be used you can do

ElmerSolver mycase.sif

to specify the sif file

although the test case looks to be correctly set up

Re: Missing the MgDyn2D Solver in Elmer FEM 9.0 GUI MPI

In the elmer directory, under share, ElmerGUI there is and edf folder and an edf-extra folder.
the magdyn xmls are in the edf-extra by default, if you copy them to the edf folder they will then show up in ElmerGUI.

Re: Transient simulation

Simulation Type = Transient Timestep Intervals = 500 ! Total number of steps to be run Timestep Sizes = 1 ! The time step increment for each step Steady State Max Iterations = 1 Output Intervals = 20 ! Make out every 20th step or below woould be the same thing with a smaller increment Simulation Typ...

I believe the original model Reynolds number was high due to the dimensions of the part (several meters), now that it has changed to micrometers it is likely different. The link to the mentioned test case is above.

Re: Tutorial 16 Flow through a hole (in MEMS microperforation)

I based the parabolic equation on the original size of the model so the equation should be adjusted for the new size. However the new model is very small. Originally the base was 4x5 meters, now it is 1.E-6 meters. What is the intended size of the base?

Re: Tutorial 16 Flow through a hole (in MEMS microperforation)

I am thinking that the pressure builds high at the boundaries where there is little flow to relieve it, and the pressure is the lowest where the most flow occurs, because the flow relieves the pressure. I will check my results for pressure to see if it matches.
