MAPDL may terminate SOLVE without us having understood the model. In M06
we will convert the solution into a testable statement: the applied force and its moment
They must be exactly balanced by the fixed support.
Your mission
You will solve the prepared beam in M05, confirm that a result set exists, and You will generate a CSV that simultaneously closes the balance of forces and moments.
Guiding question: if SOLID185 has no nodal rotations, how can fixed support transmit a moment?
Objectives
By completing M06 you will be able to:
- Explicitly declare a linear static analysis.
- Distinguish load step, substep and result set.
- Explain what states it connects
SOLVE. - Programmatically check that a solution is available.
- Read nodal reactions using
*GET. - Reconstruct a moment from translational forces.
- Use
SPOINTandFSUMwith a conscious reference point. - Accept or reject the balance through quantitative tolerances.
Prerequisites and downloads
- Have completed M05: Beam must have audited loads and constraints.
- Recognize pattern selection → check → application → restore.
- Remember the global convention: X longitudinal, Y vertical, and Z transverse.

How to use this lesson
| Track | Duration | Scope |
|---|---|---|
| Quick win | 30–35 min | Prediction, SOLVE and first reading of reactions with FSUM. |
| Complete | 65–70 min | Additionally, force and moment audit, false equilibrium hunting and linear challenge. |
Recommendation: Calculate RFY and RMZ on paper before SOLVE. Balance is the first physical validation after an apparently correct solution.
