Inverse calibration and missing Fitness Value
I have an inverse calibration loadcase wich runs without problems. It runs with a dynamic explicit solver (Abaqus). The problem is the missing Fitness value of the Loadcase. I would say, without a fitness value Mcalibration cannot consider this load case in the optimizations. Am I wrong?
My inverse model is a sphere indenting a plate. It consists of a solid indenter controlled via a reference point with a force amplitude as preset. Only CF2 and U2 are used as history outputs. RF2 is switched off, because it is always 0 (force preset). The Abaqus Model is 2D and uses CAX3 elements.
The image shows a screenshot of the loadcase in Mcalibration. The upper right chart shows the mentioned load case.
Why is the fitness value missing? What could be the problem? Is this fitness value necessary to properly consider the load case during optimization?
That sounds odd. I would be happy to investigate if you attach your files.
here are the files. Indentationtest.csv is a Abaqus input file. The website didn't allow .inp as file ending.
