<div>We could better help if you would send a .geo and .pro file.</div>
<div>You should also tell what is exactly meant with « maximum stress state ».</div>
<div>Do you mean maximum Von Mises stress ?</div>

<blockquote type="cite">Hi All,<br>
My problem is to determine the maximum stress state acting on a structure.<br>
I would therefore like to understand how the .pos file is written in order to extract the maximum value directly from the file.<br>
<br>
Then place an example.<br>
from the .pro file I calculate the stress as:<br>
{Name sigma; Value {<br>
Term {[TensorV [C_xx [] * {d ux} + C_xy [] * {d uy} + C_xz [] * {d uz},<br>
C_yx [] * {d ux} + C_yy [] * {d uy} + C_yz [] * {d uz},<br>
C_zx [] * {d ux} + C_zy [] * {d uy} + C_zz [] * {d uz}]];<br>
In Vol_Mec; Jacobian Vol; }<br>
}<br>
}<br>
and therefore:<br>
{Name stress; NameOfPostProcessing Elasticity_u;<br>
Operation {<br>
Print [sigma, OnElementsOf Vol_Mec, File "sigma.pos"];<br>
Now the .pos file is:<br>
TS (0.980007811853844,0,1.029813000728299,1.53102112193407,0,1.252665152081291,1.549809848214138,0,0.7456705669368301,1.46144890353805,0.025,1.248675086069074) {- 774520.2424171679, -23285.95950419134,4908270.764450434, -23285.95950419134, -2549506.633453323,

<br>
How should I interpret it?<br>
<br>
I thank you in advance for the help you can give me.<br>
