Hello,
When running the analysis for a concrete plate supported on elastic supports and a nodal load in the center of it, the following "error" appears:
Does anybody know what is wrong?
Thank you in advance,
Ignacio
The error is due to the fact that the two numbers after the command ELASTIC FOOTING has been entered as 0 0 whereas this is supposed to represent the length and width of the elastic footing. A sample is shown next
1 TO 6 ELASTIC FOOTING 1 1 DIRECT Y SUBGRADE 150
In the above example a size of 1 ft x 1 ft is considered as the size. For multiple nodes this size would be based on the distance between the nodes. The direction would also be Y as opposed to X.
Having mentioned that, when you are modeling the mat with a mesh of plates, you need to use PLATE MAT support instead.
