8.2 MPP coupling

8.2.1 Introduction

To enable users to easily start MADYMO and the PARTNER, the madymo_cpl program has

been developed. The madymo_cpl program is able to start two MADCL-enabled solvers at

the same time, in one shell on Linux platforms.

8.2.2 What does it do

The madymo_cpl program calls the exec2 binary, which is shipped with the MADYMO dis-

tribution. Then exec2 starts both the MADYMO and the PARTNER solver. In case one of the

solvers exits with an error condition, the exec2 program will terminate the other solver.

The process tree is given below:

The way the PARTNER solver is started differs per partner, i.e., madymo_cpl will use a stan-
