How does comsol set the lower limit of variables?
If you want to get the maximum position of a variable in the cloud image, you can right-click to add the maximum and minimum functions under this drawing group. The cloud map will show the points corresponding to the maximum and minimum values in the map. If you want to know their coordinates, you can right-click to add the drawing data to be exported and save it as a text file. There are the coordinates of the maximum and minimum values in it. If it is two-dimensional, the coordinates are x and y, and so are other reasons.

Putting an actual system on a computer for simulation will go through the following eight steps: (1) System definition: according to the purpose of system simulation, the boundary and constraint conditions of the studied system are determined. (2) Establish a mathematical model: abstract the actual system into a mathematical expression or flow chart. (3) Model conversion: the mathematical model of the system is converted into a simulation model that can be processed by the computer. (4) Design simulation experiment: Given the external input signal of the system, set relevant parameters and variables. (5) Model loading: input the converted simulation model into a computer in the form of a program. (6) Simulation experiment: Conduct various designated experiments on the simulation system in the computer. (7) Model verification: modify and test the model according to the performance requirements that the system should meet. (8) Submit the simulation report: analyze and sort out the simulation data and provide the simulation final result report.
