Thank you for sharing the file. I was able to fix the .dat file reader. But for some reason, I could not get your simulation to work. The second step - steady state dynamic - produces no results. There is only one line written in the .dat file, and no data is written in the .frd file. I have used similar model setups (with default amplitude) with success in the past. ---

Ok, found it. For the steady state step to work, you need to remove Plastic materil definition. Calculix does not throw any errors it just exits. So the analysis is considered finished. But it is not. ---

Interestingly, in version 2.1.0 everything works without problems, the created ‘inp’ files 2.1.0 and 2.3.4 are identical, except for the “Coordinates” section ---

Do you actually get the results for the 2nd step? Not only frequencies, which are the result of Step 1. If you remove the plastic definition, you have to leave the program running a little longer to complete the analysis. It will finish with a 5 GB results file. To decrease the computational time and reduce the size of the result file, reduce the number of data points to 10 in the steady state dynamic step. ---

Those are only the results of Step 1. It is written in the Status block. ---

Without defining the plastic material, it works two steps, but the cmcp48.dat file still loads with an error ![image](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/4/4291c5657edfd0aba0d9895be9f675689e1e3bec.png) ![image](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/8/8c6d499d36cd2da6f9d80931e65888790cf4640a.png) We can close the topic. ---
