The 2nd is for the complete transient operation including an ANSYS.mf with timint=on etc... The problems are: 1. without the open(Solver| thing, both system commands start at the same time, the second one does not wait for the first one to finalize. But the combination of system commands + open command does not work, either! What do You guys do, if you want to start several processes after each other? 2. second system command = restart does not work, althouth same setup in GUI works. I get errors like: +--------------------------------------------------------------------+ | ERROR #002100056 has occurred in subroutine CPLG_CheckBc. | | Message: | | An ANSYS CFX boundary condition that requires data from an external| | coupled solver (e.g. ANSYS Multi-field) has been used on | | ANSYS CFX boundary : WALL_F_S | | | | The required data is not available because either: | | - a coupling to the external solver has not been established, or | | - the external solver is not aware that it must provide the data | | (e.g. missing MFLC command in the ANSYS Multi-field setup). | +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ | ERROR #002100056 has occurred in subroutine CPLG_CheckBc. | | Message: | | An ANSYS CFX boundary condition that requires data from an external| | coupled solver (e.g. ANSYS Multi-field) has been used on | | ANSYS CFX boundary : WALL_F_R | | | | The required data is not available because either: | | - a coupling to the external solver has not been established, or | | - the external solver is not aware that it must provide the data | | (e.g. missing MFLC command in the ANSYS Multi-field setup). | +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ | ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | Failed in solver setup synchronization point. | | | | | | | | | | | +--------------------------------------------------------------------+ THX for your help in advance!!

Hi Kaiser,
Not sure if this helps. You can use multi-configurations within the same def file. Refer to: http://blog.ansys.com/2011/11/16/mul...te-simulation/ |

Thx for that link. That blog seems to be helpful, although I cannot estimate whether that strategie is applicable to 2-way FSI.
