AxisVM MESSAGES #

unnamed (1)
Question from AxisVM to the user if the selected function (e.g. “Delete”) should be carried out or about how to proceed

Cause
Some lines inside a domain do not have a node at their intersection point. The mesh cannot be generated for the domains in question

Procedure

  • Introduce Node at intersection (“Geometry” tab, Intersect function)

Cause

The listed domain contains nodes in short distance compared to the selected mesh element size

Procedure

  • “Yes” mesh generation will be tried (in many cases, successfully). The checking of domains is skipped
  • “No” interrupts the mesh generation. Affected domain is selected

Error. The selected function or calculation cannot be performed

Cause
The listed domains contains nodes in too short distances compared to the selected mesh element size. The mesh cannot be generated

Procedure

  • Check model and avoid short distances between nodes and/or lines
  • Choose a smaller mesh size

Cause
Inside a domain nodes are placed too close to an edge

Procedure

  • Check node position
  • Use function “Geometry check” (on “Geometry” tab)

Cause
A node or a line is placed at a very short distance to the domains edge or lines intersect at a very acute angle. Due to the set editing tolerance, the program attempts (without success) to merge these objects.

Procedure

  • Check model
  • Avoid short distances between nodes and/or lines
  • Enlarge intersection angles
  • In special cases, change tolerance settings (“Settings“ → “Model options” → “Editing tolerance” )

Critical note. Important information, violation of code provisions, untrustworthy results

Cause
When deleting the mesh, seismic loads (response spectrum/pushover method) are also deleted

Procedure

  • Parameters for seismic load generations are preserved
  • Recalculation of vibrations is necessary

Question from AxisVM to the user if the selected function (e.g. “Delete”) should be carried out or about how to proceed

Cause
Result of the “Mesh check”. Heavily distorted elements are triangles with a smallest angle <15 or quadrangle with a smallest angle < 30

Procedure

  • Check mesh manually
  • If needed, modify the model and/or the parameters for mesh generation
