Hi Noura
Please give the version of the Ansys product you are using whenever you ask a question here (can really help determine how to answer a question). Also what do you mean be '...reads the chart in ansys...'? Ansys is not a product so I'm not sure what you are asking here. I guess about WB Mechanical? If so which chart? A scree shot may help.
Are you using the method given by MathWorks on their community page? If so I'd pose this question there.
If you are using the MathWorks toolbox you may want to explore the world of PyAnsys instead here. PyAnsys is a set of language libraries, right now for Python (mainly), that allows us to interact with different Ansys products. Â
