Hello,<\/p>\n

 I am doing cyclic symmerty simulation in static structural <\/p>\n

here is the symmerty model <\/a><\/p>\n

and i defined the frictional contact of 0.06 coefficient friction <\/p>\n

here is the contact information <\/a><\/p>\n

 <\/p>\n

here is the analysis settings of step 1<\/p>\n

<\/a><\/p>\n

here is the analysis settings of step 2<\/p>\n

<\/a><\/p>\n

and here is image shows the loading condition <\/p>\n

<\/a><\/p>\n

 <\/p>\n

and boundary condition is shown here <\/p>\n

<\/a><\/p>\n

 <\/p>\n

but still im getting this error<\/p>\n

Element 258486 (type = 4, SOLID187) (and maybe other elements) has become highly distorted. Excessive distortion of elements is usually a symptom indicating the need for corrective action elsewhere. Try incrementing the load more slowly (increase the number of substeps or decrease the time step size). You may need to improve your mesh to obtain elements with better aspect ratios. Also consider the behavior of materials, contact pairs, and\/or constraint equations. Please rule out other root causes of this failure before attempting rezoning or nonlinear adaptive solutions. If this message appears in the first iteration of first substep, be sure to perform element shape checking.<\/strong><\/p>\n

 <\/p>\n

 <\/p>\n

i dont no how to solve this problem <\/p>\n

i changed element size also and i changed time step also and i changed number of substeps also but still model is not converging <\/p>\n

 <\/p>\n

can anyone please help me to solve this <\/p>\n
