This widget is a table to set anisotropic conductivity on specified elements. It is a complex component but behaves the same way as many SYRTHES tables.

In first column, one finds for each line check boxes. The purpose of the check box is to save (as comment not interpreted by SYRTHES) a setting we want momentarily discard. When trying different conditions, it may be interesting to comment a previous try instead of purely erasing it, and be obliged to retype it to come back to the previous parameters. This has been introduced in the SYRTHES interface to mimick the possiblility to simply activate or not a command or a condition by simply adding or removing a "/" in first column of the ASCII SYRTHES file.

The second column allows to choose between three possibilities :

Constant is indicating a constant isotropic conductivity (lambda_x lambda_y in W/m2 but also an angle in Deg) on a collection of elements identified by their reference.

Function follows the same principle but the setting of the conductivities along x and y and the angle to change the coordinate system may this time be a function in which several parameters can be included :

Warning : no blanc is authorized in that string (type it the way you would write the corresponding C code).
Examples : 20+5*sin(0.01*y), 3*pow(x,2)

Program corresponds to configurations which cannot be handled with the two previous conditions. In that case, user will have to fill the corresponding C program which can be accessed through the window User C function. Still, users have to define the elements concerned by that condition in indicating the reference of these elements. This is compulsory to allocate the required memory.

"References" corresponds to the list of references concerned by that conditions. One underlines that user may replace a long list of references by several lines. The "-1" pseudo reference indicates on all elements. The usage of this special condition may turn to be a bit tricky in complex case. For example you cannot specify it if somewhere you have orthotropic or isotropic material, because it would mean that some elements are both anisotropic, isotropic and orthotropic.

"User comments" allows to put a short description about the group of elements concerned and the conductivity set.
