Hi,<\/p>\n

I am trying to vary the young’s modulus of a hollow cylinder. In my case, the Young’s modulus decreases radially.<\/p>\n

I followed the instructions here https:\/\/www.padtinc.com\/2022\/02\/03\/hold-my-beer-spatially-varying-materials-in-ansys-mechanical-made-easy\/
for a cube and applied it to a hollow cylinder.<\/p>\n

Since the model I am working with is symmetrical, I have set up quarter symmetry and my final result is shown below.<\/p>\n

<\/p>\n

Figure 1 – Source Points & Score<\/p>\n

<\/p>\n

Figure 2 – Material Plot <\/p>\n

<\/p>\n

<\/p>\n

Figure 3 – Young’s modulus vs Score<\/p>\n

 <\/p>\n

Figure 2 shows the young’s modulus changing radially but the minimum value is not 1E+9 as shown in figure 3.<\/p>\n

 <\/p>\n

So, my questions are,<\/p>\n

    \n
  1. Why is the minimum value not what I wrote and how can I fix it?<\/li>\n
  2. How many source points do I need to map the material properties accurately?<\/li>\n<\/ol>\n

     <\/p>\n

    Please let me know if you need more information.<\/p>\n
