To assess the accuracy of the collected data, the interpolation software and the finite element engine, a series of 2D simulations were conducted. Simulations of transverse aspects of neural tube development (Fig. 11) were found to be generally consistent with those obtained by Clausi and Brodland (1994). Which study’s simulation best represents actual embryos is not yet known. The differences between the simulations are apparently due to differences in how the contraction forces are calculated: Clausi and Brodland used non-linear truss elements, whereas the current study uses cellular fabric.
