After solving a model with Member Area Loads, RISA-3D will automatically create Transient Basic Load Cases that allow the user to verify load distribution.
For information on how to view this distribution, please see the article "Using Transient Loads to Verify Applied Area Loads in RISA-3D".
If this load attribution is not what you’d expect, you can adjust the Area Load Mesh entry, which controls the fineness of this distribution.
This feature is located on the Solution tab of Model Settings:
If you have a model with closely spaced members, you can lower this value to achieve a finer area load mesh and therefore a more accurate load distribution.
