Subject: Request for Assistance in Combining ANSYS Mechanical .rst Files from Separate Simulations in Sequence<\/p>\n
<\/p>\n
Dear Support Team\/Forum Members,<\/p>\n
<\/p>\n
I am reaching out to seek guidance or a potential solution for a specific challenge I am facing with ANSYS Mechanical APDL result files (.rst). My objective is to combine results from two separate simulations into a single .rst file, without performing any algebraic operations on the results themselves. I aim to achieve a sequential arrangement of Load Step results within one consolidated .rst file, akin to the outcome of running a single simulation with multiple Load Steps in sequence.<\/p>\n
<\/p>\n
**Background:**<\/p>\n
I have conducted two separate static structural analyses on the same finite element model, which shares identical geometry, material properties, mesh, and contact conditions. However, each simulation is subjected to a distinct load condition:<\/p>\n
<\/p>\n
1. **Simulation 1:** Applies a force in the Z direction, resulting in a .rst file (let’s call it `fileZ.rst`).<\/p>\n
2. **Simulation 2:** Applies a force in the X direction, resulting in another .rst file (let’s call it `fileX.rst`).<\/p>\n
<\/p>\n
Each .rst file contains the results for its respective Load Step, and I can plot these results individually from each file in ANSYS Mechanical.<\/p>\n
<\/p>\n
**Objective:**<\/p>\n
My goal is to concatenate the Load Step results from `fileZ.rst` and `fileX.rst` into a single .rst file (let’s call it `fileCombined.rst`). This file should contain the results of the Load Step from `fileZ.rst` followed by the results of the Load Step from `fileX.rst`, without any modification to the results data itself. The desired outcome is similar to what would be obtained if I had run a single simulation with two Load Steps in sequence: one for the Z direction force and another for the X direction force.<\/p>\n
<\/p>\n
**Challenges:**<\/p>\n
– I aim to avoid re-running the simulations due to their costly nature.<\/p>\n
– Direct manipulation or merging of .rst files is not straightforward due to the structured and indexed format of ANSYS result files.<\/p>\n
– ANSYS documentation and forums have not yielded a direct solution for merging .rst files from separate simulations in the manner described.<\/p>\n
<\/p>\n
**Request:**<\/p>\n
I am seeking advice, scripts, or methodologies that would enable me to achieve the aforementioned objective. Specifically, I am interested in any ANSYS Mechanical APDL commands, scripting techniques, or third-party tools that can facilitate the combination of .rst files as described, while preserving the integrity and sequential order of Load Step results.<\/p>\n
<\/p>\n
If anyone has encountered a similar challenge or has insights into potential solutions, I would greatly appreciate your input. Additionally, if there are alternative approaches to analyzing combined effects of different load conditions without re-running simulations, I am open to suggestions.<\/p>\n
<\/p>\n
Thank you in advance for your time and assistance.<\/p>\n
<\/p>\n
Best regards,<\/p>\n
