Hi 

i am writing an abaqus scripting to read temperature from ODb file. after i get temperature, i do a calculation and save in a new step, new frame and new field. i did this successfully. but , now i want another modification. i want to start calculation to each node when temperature of each node's exceeds 80 Celsius. then i tried to read temperature by node by node. then i did calculation and write, myField.addData(field=Total_value).

then it gave message as index error. anyone know how this kind of task is done?
