Re: Maximum stress location

Hi<br />
<br />
the first argument is the variable (T(x,y,z,t) in your case, but you write just T) and the second argument is a charachter "x", "y" ...<br />
Once you have defined the maxop1() operator in the definition, you must solve your model (or update it if already solved before you defined the maxop1) <br />
<br />
Then under Derived Values you define a global value and enter maxop1(T,x), duplicate it 2-3 times and replace the x, by y then z respectively<br />
<br />
The result in the table should be the coordinates of the maximum over the domains, or boundaries defuned under the maxop1() operator tab<br />
<br />

Good luck<br />

Thank you for fast answer. I did find a post about it, however I don't know how to do the following<br />
<br />
Define a Maximum coupling operator, then pass in the independent variables as a second argument to query the location at which the maximum occurred. For example, say you solve for temperature, T, and you have a Maximum coupling operator, maxop1, then use:<br />
<br />
maxop1(T,x) for the x-coordinate at which the maximum occurs<br />
maxop1(T,y) for the y-coordinate at which the maximum occurs<br />
<br />
Can you please tell me where exactly I do this?<br />
<br />
Thank you<br />
<br />

Hi<br />
<br />
search the FORUM for max( it has been discussed a few times, its also (slightly hidden) in the help files you need to call the max(u,x), max(u,y) or max(u,z) to get the three coordinates x,y,z of the maximum of your dependent variable "u" (example for a solid physics case)<br />
<br />

Good luck<br />

Hi everyone, I have a simple question. I am trying to find a location of maximum stress on my model, but somehow I cannot find out how to get it. Can anyone please help me with that?<br />
