@carpanes Seems pf_active.time (51 points) is the same as pf_active.coil{index_coil(1)}.current.time so if set in coil should remove from top and set homogeneous to 0. OK?

At a first glance I would say that all the currents share the same time, so we could also put homogeneous = 1 , and provide the time directly there, removing the other one. However, the field pf_active.coil{ii}.current.data and pf_active.coil{ii}.current.time was filled this way by CORSICA data originally so we might not want to change remove the original data.

Yes better keep local tim/data
