Command manual

This manual describes the different simulation model commands in our software. It covers both the structural input format and mathematical formulations. Many small examples show how to use the different commands.
The manual is integrated into the software. It automatically shows the command and highlights the parameters that the user is currently is working on.

Web based version of the command manual can be accessed here:

Verifier documentation

Each released version of IMPETUS Afea Solver’s computational modules (FE and DP) is subjected to version control based on a benchmark database. We test all our input commands to verify that they work correctly. For some applications, Recommended Modelling Practices (RMP) have been developed. The RMPs contain validation tests in combination with a recommended modelling methodology. All of the following documents are updated based on the latest version control:

Verification of Input Commands
Verification of Explosives
Verification of HIII Dummy, Male, 50th percentile
RMP001 - Material Failure Prediction Of Large-Scale Steel Structures
RMP002 - High Explosive Blast Loading
RMP003 - Recomputing DNV-RP-C208
RMP004 - DOCOL Steels
RMP005 - Ballistics
