| | ''filename'' | string | Filename of the data files involved in the SPACAR simulation. If omitted, filenname 'spacar_file' is used. | | | ''filename'' | string | Filename of the data files involved in the SPACAR simulation. If omitted, filenname 'spacar_file' is used. | |
| | ''transfer'' | ''true'' | Calculation of state-space equations. Requires specification of at least one input and one output, by means of ''nprops(i).transfer_in'' and ''nprops(i).transfer_out''. Cannot be used with applied forces, applied moments, prescribed displacements, and buckling load multipliers. | | | ''transfer'' | ''true'' | Calculation of state-space equations.

| | ::: | 1×2 cell | Calculation of state-space equations that include relative damping for all modes of the system. (This value only affects the output in ''out.statespace''; the eigenfrequency output in ''out.freq'' and Spavisual remain undamped.) For example: ''opt.transfer = {true 0.01}'' calculates state-space equations with relative damping 0.01. | | | ::: | 1×2 cell | Calculation of state-space equations that include relative damping for all modes of the system.

| |''customvis''| ''{'modeshape','maximum 20'}'' | The maximum number of mode shapes, in this case 20, that are shown in the Spavisual window.

| | | ''spavisual'' | ''false'' | Do not show the Spavisual window after a simulation. | |
| | | ''rigidstress'' | ''true'' | Consider the stress in rigid elements when computing the maximum Von Mises stress in ''opt.stressmax''. By default, this option is false and stress in rigid elements is ignored. | |
| | | ''stressperelement'' | ''true'' | Compute the maximum Von Mises stress per element, stored in ''out.step(i).element(j).stressmax'' for element ''j'' at step ''i''. | |
