Re: Merging Debian package patches

Hi Adam, first, thanks for your continued effort on keeping the repositories to date! At the moment I seem to be happy with the state of the simulator, so I somewhat hesitate to make just some update test runs on my work machine. But I am quite sure I'll return to this thread some time in the future...

Re: Stop simulation on variable value

Hello Matthias, "stop simulation" should not provoke an error, but just not execute the remaining steps in the transient simulation. Is this possible? How? As a quick&dirty workaround you could write the results of some variable (the temperature at certain points / lines) into a file b...

Re: Visualize boundaries

Hello Peter, motivated by Thomas' question, here is a related one: If I use a partitioned mesh (to exploit a QuadCore) I obtain inner "boundary surfaces" displayed in ElmerPost's color mesh for my 3-d objects at the positions of the calculational partition borders, even if I check to displ...

Re: How to display an additional field variable?

Hello Thomas,

yes, I confirm your method! Thanks a lot!

Although, I think it is still somewhat queer that the density by itself cannot be saved, and needs a duplication of otherwise identical definition code.

Kind regards,

Peter

Re: Merging Debian package patches

Hello Adam, yes, I guess I was not aware that also a source package is available as a repository file. I built the binary files myself after downloading them directly from the SVN server, and to my knowledge there was no direct information on which packages to fetch on a mandatory base. It was again...

Re: Defining surfaces and volumes

Hello Bill, I am confused about how to define the surfaces that will be used to establish the volumes. Can surfaces be defines such that parts of that surface may be parts of another surface, or must all surfaces be non-overlapping? Being somewhat a novice myself still and struggling with the genera...

Re: How to display an additional field variable?

Hello Peter, I changed the definitions according to your suggestion, and the simulation starts - hoorray! :D But right at the beginning the solver log window already fusses around: ... MAIN: Reading Model ... Model Input: Unlisted keyword: [parameter 1] in section: [solver 2] Model Input: Unlisted k...

Re: How to display an additional field variable?

Hi Peter, You could check the SaveMaterials solver (included in the SaveData module) for the purpose. See Models Manual for more details.r Did it, but presumably wrong: Referring to the Models Manual, p. 155, I entered the following solver: Solver 2 Exec Solver = after timestep Procedure File "...

Re: Gradual Timestepping

So I want the first 60 timesteps to have a size of 1 s. After that, I can do with having timesteps of about 5 s. What I want to know is if there's a way to make this transition gradually, so for example, my timestep size goes 1, 2, 3, 4 and then stays at 5. Well, as a slight variation of my given s...

How to display an additional field variable?

Hello Elmerers, I (re-)define the material property "density" for a fluid that represents a mixture of a viscous liquid with small amounts of immersed air bubbles. This is done by a MATC statement: Material 1 ... Density = Variable Pressure Real MATC "max(0.0001 866/(1+0.09*(1/tx)))&q...
