endUnits¶
Abacus does not have a unit system. You need to use everything based on SI/SI(mm) units.

Files¶
| Gets updated when | Cleared when | ||
|---|---|---|---|
.cae | Project file | Interact with GUI | Never |
.rpy | Replay Python file Allows to recreate the model Contains all used actions Only 5 recent versions of replay files will be retained | Interact with GUI | New session starts |
.jnl | Journal/Log Stores used model-related commands Allows to recreate the model if model database gets corrupt | Save model database | Never |
.rec | Recovery file Stores unused model-related commands Useful if Abacus aborts unexpectedly | Interact with GUI | Save CAE file |
.odb | Output DataBase from modelling stage Analysis result data & model-related info: Nodes, elements, surfaces, sets | ||
.inp | Input configuration file for analysis stage | ||
.rpt | Report file | ||

Types of Objects¶
Properties¶
- Deformable
- Rigid Discrete
- Rigid Analytical
| Object treated as | |
|---|---|
| Deformable | Block that deforms due to forces |
| Rigid | Solid block that cannot be deformed |
| Discrete | “mesh” of atomic “discrete/finite elements” |
| Analytical | Bounding box |
Geometry¶
| Shell | |
| Wire | |
| Point |
Mesh Element Type¶
| Type | |
|---|---|
| Triangular CPS3R | Faster computation |
| Quad CPS4R | Better geometric precision |
| Quad-Dominated | Compromise between both |
Views¶
| Feature Edges |
Properties of Mesh¶
| Value when mesh is broken | |
|---|---|
| PHILSM | 1 |
| PSILSM | 0 |
Export¶
Image¶
- Open ODB
- Display ODB to viewport
- Set field output to viewport
- Adjust view commands
- File > Print > File
Field Report¶
Method to output data at desired locations, for a single frame within a single step at a time
Procedure¶
- Report
- Field Output
Display Group¶
- Create display group
- Pick from viewport
Speed Up Simulation¶
- Decrease time period to 0.1
- Increase max increment size
- Useful if you are just interested in final output only
- Use more cores
- Reduce output requests
- Reduce mesh in unnecessary portions
- Check element formulation
- Use Reduced integration/linear geometric order
- Use small artificial damping
