I need to recreate the formula for determining the minimum protective layer of concrete. In the formula there is a choice of the maximum value in curly brackets. How do I use this program to make the minimum protective layer of concrete equal to the maximum value in a curly bracket and greater than or equal to 10 millimeters.

c_min=max{c_min,b;c_min,dur+c_dur,y-c_dur,st-c_dur,add}>=10 mm

In fact, it would be advisable to send the sample sheet. Something is not convincing (the braces in Smath are not used). However, the "max" function provides for evaluating the maximum value of a vector internally; then you can put in a vector all the elements to choose the maximum (including "10mm". Alternatively, the "Max" function contained in the "Custom" plugin (you have to install it from a special menu) directly accepts the lists.
