extracting free surface_vertical slosh

Hello,
This post i'm reposting from the OF post processing forum, since it is mainly on paraview. I'm using OF2.3.1 with ParaView 4.1.0 for my project. I'm studying the sloshing problem in rectangular tank with horizontal and vertical excitation applied separately. The excitation is through input displacement generated through gen6DoF application. i could do the horizontal excitation case and extracted the free surface at various x locations of the tank (tank base is in x-z plane) as explained in spillway tutorial, using paraview option. 'https://www.hpc.ntnu.no/display/hpc/OpenFOAM+-+Spillway+Tutorial' But while doing the same procedure for vertical excitation and trying to extract the free surface, in all variables (alpha.water, U, p...) the data is 'nan' for all possible x locations of tank. But visually i could see the surface oscillation in tank. The possible reason for 'nan' i could find is, the line over which variables are integrated is going out off the flow domain in all time steps, because the line is not moved with tank. Since my tank is moving vertically up and down with time, in most of the time steps the drawn line goes out of flow domain. Is there any way to fix the line to tank or any other possible way to overwrite all nan values to zero. Please help me to overcome this issue. Thank you, |
