From PrePoMax to cloud HPC
PrePoMax (https://prepomax.fs.um.si/) is an opensource user interface to Calculix. Thanks to this, you can easily generate the input file to use for any Calculix analysis. Once the input file is generated, it is also possible to benefit of remote hardware resources provided by cloudHPC and speed up the solution time of your analysis.
Obivously, once the simulation is completed on the cloudHPC you can go back to PrePoMax by opening the results of your analysis. This closes a complete loop of opensource and cloud based software which allows every engineer or designer to run finite element analysis.
