J Integral with dynamic explicit

Hi,

I am trying to solve a 3PB specimen with a notch. I am doing the dynamic explicit analysis. I want to find the J-integral. Giving the J-integral as history output. Trying to run it gives following error.

---------

***ERROR: THIS KEYWORD IS NOT AVAILABLE IN Abaqus/Explicit

 LINE IMAGE: *contourintegral, crackname=H-OUTPUT-2_CRACK-1, frequency=0,

             normal, contours=2, cracktipnodes

----------

Running the same for dynamic implicit analysis works fine.

Please help me regarding this. Can't contour integral be calculated with Dynamic explicit analysis?

Thanks,
