sampling when mesh has moving points
Dear all,
I am trying to sample along a line for a mesh where points move, hence, when the initial cells where the line is located move away I get an error and the sampling process is aborted: Code:
Time = 0 Just to clarify, I want to measure always at the same location, it does not matter at which cell. Best, Pablo |
Hi Pablo,
What version are you using? I have had similar problems in the official release, but never in 1.6-ext. I never came across a solution, though. Good luck, Niels |
Hi Niels,
we are currently using 2.1.1. Good to know, I will then try to dig my way out of here programming... Thanks! |
Does this problem happen when only a part of your line I'd out of the domain or only when all the line gets out?
By the way, what can of deformation do you use? Translating? |
Hi,
actually my line is always within the domain. The problem arises when any location of the line starts to belong to other cell than the initial one. I am using a modified version of dynamicMotionSolverFvMesh. Best, Pablo |
Can you use a post treatment software like EnSight or ParaView? It would make the thing easier (but longer)
|
Definitely.
There is another option which I currently use: sample for free surface as an isosurface, and then by using a python script I obtain the time series of free surface elevation anywhere. This is kind of brute force, though. |
