Hi,<br><br>I'm encountering some problems when scaling the "A" (creeping parameter) for the non-newtonian rheology.<br>In gale user manual (2.2.8.2) it is said that the unit of A parameter is <i>s(-1/n).Pa(-1)<br>
</i>For other authors the unit of this parameter is most of the time in <i>Pa(-n).s(-1)</i> or <i>Pa.s(1/n).</i><br><br>I will take an example in order to understand :<br><br><br>A = 262800<i> Pa.s(1/n)</i><br>n = 4<u><br>
<br></u>If I want to translate this value for gale, first I have to change the units for <i>s(-1/n).Pa(-1) </i>by multplying with ^(-1) ?<br><br>Then A unscaled becomes for gale 262800^(-1) = 3.8051e-6<br><br>Based on that and following gale user manual A scaled for gale is 3.8051e-6 * (10e25)^(1/n) = 6.7574 <br>
However in the dyke example the scaling of A is around 1e-12.<br><br>I'm wondering if there a mistake for the given scaling equation. Maybe this equation should be Anew = Aold(10e25)^(-1/n) ?<br><br>When I use this, I obtain Anew = 2.1368e-12 and this works<br>
<br>Do you have any suggestions about this ?<br><br>Nicolas Riel<br>
