I was wondering how the sheet angle is defined in openCARP. I found in the documentation this:
|sheet_endo||float, optional Set the sheet direction on the endocardium|
|sheet_epi||float, optional Set the shhet direction on the epicardium|
but it is not clear to me what the sheet angle exactly is. Does it specify the angle the normal of the sheet makes with the horizontal plane of the endocardium/epicardium? Or is it the angle with the "z-axis"?
Do you maybe have a reference to a paper/drawing?
Thanks a lot for the information!
