I can&#8217;t seem to find an error message.&nbsp;&lt;br&gt;2) Again starting afresh, if you Design -&gt; History Tracking -&gt; Try and change the material:&lt;br&gt;You get two messages. <img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/15-07-2026-1784132496-mceclip0.png\" \/> and <img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/15-07-2026-1784132533-mceclip1.png\" \/>. &lt;br&gt;However, if you simply make a 3D object. Then you can change the material with history tracking still enabled. Clearly I changed the material with History Tracking enabled. You can also make it a fluid.&nbsp;&lt;br&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/15-07-2026-1784132772-mceclip3.png\" \/>&lt;br&gt;Both of these seem like simple bugs.
