Hello,

I would like to extract the element id of SSP-BRICK elements from nodes ID or coordinates. Could you help me with this?
The nodes data are saved in the following format:
node_data = {
'Node ID': [node.id for node in NODES],
'X Coordinate': [node.x for node in NODES],
'Y Coordinate ...

Hello,

Sorry for my oversight. I wanted to apply a face load. The equation that I want to have is:

-392.4*(z==-100) -9.81*0.707*(-60-z)*(z>-100)

The graphic representation is shown in the attachment.

Thank you.

Dear STKO team,

I would like to use the face mass condition to assign a value of load depending on the z-coordinate. I want the load to be -392.4 when the z-coordinate is equal to -100 and take a value according to the following equation when z>-100:
-9.81*0.707*(-60-z). I have tried the following ...

Dear STKO Team,

Would it be possible to share the latest available STKO Linux version?

Many thanks.

Kind regards,
Konstantinos

I fixed the issue. Just for the information of other users, I am using the SSPBrickU-P element. In this element, the water pressures are calculated by performing a transient gravity analysis and the water pressures are not included in the reaction force, but in the reaction force included dynamic ...

Hello,

Shouldn't the reaction forces already include the horizontal component of the hydrostatic pressure from the previous phases? If yes, there is no reason for a loss of equilibrium. If not, then it makes sense to have this expansion in the bottom part. Do you know perhaps what is the possible ...

Many thanks for the reply.

The ASDAbsorbingBoundary element seems to be recommended primarily when excitation originates from outside the model. Additionally, if I attempt to apply absorbing boundaries on only one side of the model, this element doesn’t work.

I’ve set up a simpler model with ...

Dear STKO,

I am trying to simulate a moving load in a saturated medium. Since the source is inside the model, I have to use the distributedLK3D function in the lateral boundaries to model the absorbing boundaries. In addition, in order to reduce the number of nodes, I have constrained kinematically ...

Thank you very much for your immediate reply. It was really helpful!

I modified the script a bit, as the load was applied simultaneously on multiple locations based on the partitioning of the mesh.
Below the updated script where the load is applied on every node at a time based on the y_coord and ...

Dear all,

I want to run a simulation of a moving load on saturated porous media. For this purpose, I created a TCL script that applies a vertical load to nodes along a line. The node coordinates are read from the nodes.tcl file.

The script was working as expected when I used the SP solver. However ...
