Dear User,
I just downloaded your file and had a look. Your model is not running because it is singular. However it is singular because all geometries in your model are disconnected from one another.
Looking at your file I understood that you are trying to model using a "orphane mesh" approach, i.e. the typical procedure used in softwares like SAP2000 or MidasGEN, where you draw nodes, and then elements connecting those nodes....
This is not the way you should use in STKO.
STKO is a geometry-based modeler, like Abaqus, where you draw and work on CAD geometries, and at the end you do the mesh, thus discretizing that continuous geometry into a set of nodes/elements.
I give you a small example. Let's say you want to create a simple model with 2 nodes and 1 element connecting those nodes.
You followed this wrong approach:
- create vertex 1 at position (X1, Y1, Z1)
- create vertex 2 at position (X2, Y2, Z2)
- create a line from vertex 1 to vertex 2.
- mesh with option "uniform by divisions". This will create 1 element per edge
- At this point you think the line is connected to vertex 1 and vertex 2, but this is not true, you just used the previous 2 vertices as O-Snap points... but they are not connected to the line. In fact, following this procedure you have 3 geometries, 2 vertices + 1 line. Then when you mesh the model you will have 4 nodes (1 for each vertex and 2 from the line) + 1 element.
You should follow instead this correct approach:
- create a line from position (X1, Y1, Z1) to position (X2, Y2, Z2)
- mesh with option "uniform by divisions". This will create 1 element per edge
- at this points you have only 1 geometry, that generated a mesh with 2 nodes and 1 element connecting those nodes.
So keep in mind this rule:
If you have N geometries in the worktree, they will generate N disconnected meshes. Sometimes this make sense, because for example you want to create separated geometries and then use an interaction to define a kinematic constraint between them. But if you want 2 meshes to shared the same nodes, you shoule make just 1 geometry.
I could try to change your file to explain you how it should look like, however I do not know what you really wanted to achieve.
Try to follow the notes I gave you above, and have a look at our webinars. If you still have problems, send us a sketch of the porblem you want to model, so that I can modify your file accordingly
