<div class="gmail_quote"><font color="#000099">Dear GROMACS users,<br><br>While simulating a DLPC membrane, I noticed that it tends to diffuse along the normal (Z-axis) component. Is there a 'standard' restrain that is used to prevent such diffusion?<br>
The first option I thought was to restrain the center of mass of the whole membrane along the Z-axis, but I don't know what is a reasonable value for the force constant.<br>If anyone has any experience dealing with this kind of problem, please do reply.<br>
<br>Best regards,<br clear="all"></font><span style="color:rgb(0,0,153)">Jose M. Borreguero</span><br><br>
