 <\/p>\n

<\/p>\n

sorry for my poor english. I’m total beginner in this field so I need your help.<\/p>\n

<\/p>\n

I have a rotating shaft with a gear.<\/p>\n

<\/p>\n

My goal is to analyze how much friction heat is generated from the rotation with frictional contact.<\/p>\n

<\/p>\n

Used codes are the followings :<\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

– geometry, for bodies (rod, gear) :<\/p>\n

<\/p>\n

   et,matid,226,11 (gear)<\/p>\n

<\/p>\n

   et,matid,226,11 (rod)<\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

– frictional contact with coefficient 0.4 : <\/p>\n

<\/p>\n

   keyopt,cid,1,1<\/p>\n

<\/p>\n

   rmodif,cid,15,1<\/p>\n

<\/p>\n

   rmodif,cid,18,0.5<\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

– named selection(all bodies) as ‘them’ : <\/p>\n

<\/p>\n

   sf,them,conv,680,22<\/p>\n

<\/p>\n

   allsel,all<\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

and as i press the solve button i got this error:<\/p>\n

<\/p>\n

 Element type 1 is not the same shape as SOLID226.  Switching to a      
 different shape is not allowed while elements of type 1 exist.   <\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

how to solve this error?<\/p>\n

<\/p>\n

i referred this vid.  <\/p>\n
