Hello,
In the postprocess, I want to get the result of a specified point (with the coordinate (x,y,z), not just the nodes) at the current step. Is there any Gid_Process or Tcl process that can achieve this requirement?
I think it is similar to the PointEvolution command, but I don’t want to generate the graphs, and only the result of the current step is needed.
Looking forward to your advice!
Thanks.
This command doesn’t exists, and seems useful, we will study to implement it for future developer versions.
Nowadays you can do your own Tcl procedure:
a) Finding the element where the x,y,z lies, if any (maybe the coordinate is far outside) and then ask the result of the element (in case of ‘gauss-points’ elemental result) or the result of the element’s nodes (in case of ‘nodal’ result), and interpolate from these values to the new x,y,z location (based on the FEM shape-functions).
b) Creating as you said a new point evolution graph, getting the point corresponding to the current time step, and deleting this auxiliary point graph.
