| * Get the development version of SPACAR Light that supports the ''opt.customdyn'' field. See the [[https://github.com/precision-utwente/spalight/tree/contact|development branch on GitHub]]. | * Get the development version of SPACAR Light that supports the ''opt.customdyn'' field. See the [[https://github.com/precision-utwente/spalight/tree/contact|development branch on GitHub]]. |
| * Use ''opt.customdyn = 'usersig PUSHSIG';'' to have Spacar call the m-file PUSHSIG.m (all of this is case-sensitive) | * Use ''opt.customdyn = 'usersig PUSHSIG';'' to have Spacar call the m-file PUSHSIG.m (all of this is case-sensitive). This file should be in the same folder as the main SPACAR Light script. |
| * This m-file will be called repeatedly, depending on the number of ''opt.loadsteps''. This file contains a function with very specific input and output requirements. If you deviate from the template, you'll very quickly run into errors. Within this function, you'll have available the ''x''-vector, which contains the current positions of all nodes. This information can be used to create custom force profiles. Unfortunately, the node numbering in Spacar (full) is different from SPACAR Light. This is actually by design, and something you usually shouldn't have to deal with. Here, though, you do. The conversion is simple and detailed in the file. Note that this simple conversion may not work whenever you use multiple elements per beam with ''eprops(i).nbeams'' > 1. (The .dat-file shows what the actual conversion should be in all cases.) | * This m-file will be called repeatedly, depending on the number of ''opt.loadsteps''.
