Acceptable value for obtusive triangles https://dlt-acc.firelay.cloud/en/c/message_boards/find_thread?p_l_id=4041874&threadId=4391546 2026-05-12T15:59:56Z 2026-05-12T15:59:56Z Julius Schlumberger https://dlt-acc.firelay.cloud/en/c/message_boards/find_message?p_l_id=4041874&messageId=4391545 2021-01-17T10:50:28Z 2021-01-17T10:50:28Z

Dear all,<br />in the manual it is mentioned that obtusive trianlges are bad for the computation. However, neither a threshold value or recommended way to deal with existing obtusive elements is mentioned.<br />I have a grid (2.3 mio elements), which meets the recommended grid properties for orthogonality ( &lt; 0.05), smoothness ( &lt; 20), and circumcenter distance (merged elements using the default minimum circumcenter threshold of 0.1). When selecting the &#39;obtusive triangles&#39; property in View in RGFGRID, it shows me around 200 grid cells with have a obtusiveness of &lt;= 2. <br />I am now wondering, whether this is a problem, if so, how I could solve it the best way (in case another way than manually adjustment exists) and what threshold I should strive for.<br />Are there any suggestions or comments?<br />Thanks in advance, <br />all the best,<br />Julius
