This issue is for collecting requirements and some first ideas about damping as a material property. The goal is that the damping characteristics of the limb, just like its elastic...
Maybe as a dedicated plot, perhaps even include the distribution of bending stiffness as well. Also more detailed mass output generally. Masses of the various layers, mass of the string...
Currently the unit of a parameter in the bow model depends on the group/quantity that the parameter belongs to, e.g. "length", "force", "mass" or whatever. But sometimes it would be...
**Specific Issues** - [x] The error messages starting with "Layer" and "Material" should contain the name of the problematic layer or material - [x] ~Import of old models that contain...
I would like to get rid of the items "Masses" and "Damping" in the model tree and instead group those parameters by the component they belong to. The additional masses...
User manual - [ ] Document that files older than 0.7 are no longer supported - [ ] Document changes to the inputs and outputs - [ ] Input/Output formats:...
When experimenting with different variants, it could sometimes be useful to disable selected features of the current bow model, like layers and profile segments. Maybe a menu item "Enable" or...
The results of comparing VirtualBow's beam elements with reference solutions ([GXBeam](https://flow.byu.edu/GXBeam.jl/v0.5/)) for static/dynamic example problems are already pretty close, often almost identical. Definitely good enough for our purposes. There is...
From the maximum permissible stresses of the materials in the bow (#64, #232) and the volumes of the layers we can compute the amount of elastic energy that the limbs...
Some possible improvements for performance and/or robustness: * Adaptive step size control * Modified Newton iterations * Line search Some of that (e.g. modified Newton) might also improve the dynamic...
