I want to map a temperature field to my structure model, because my temperature model require a big mesh size, and to avoid some structure node  influenced by other temperature(position close to each other but different temperature), i use the "DRIVING ELSETS" to map each part temperature, but when i use this, it can not work, say that:SYSTEM ERROR IN PRE_FILLBUCKETSOFELEMS. BUCKET DATA STRUCTURE OVERRUN. My structure model can work, and temperature field is ok, if i do not use "DRIVING ELSETS", map it directly as a predefined field, it can work( do not care the precision). I have found that which part will give the error(this part looks strange and complex), if i reduce the number of  node of that part in the set, it can work, but how to solve this problem, i guess it is because the model is too big, if use DRIVING ELESETS will cost more memory than directly map it, but I found the memory space is quite enough ,as follow how to solve this problem, thanks
