Hello fellow ODE users,

     I am new to ODE and am designing a 3D app that will use ODE for =
physics but I have some questions that maybe you pros could help with.

    In short, the basic scenario that I need help with is what to do in =
the case of explosions. =20
     When explosions occur, an expanding blast radius must exist that =
expands from the point of detonation.  I know how to create an expanding =
body/geom structure that could force objects outside of its blast radius =
but that is not entirely the desired effect.
     The desired effect is such that the shockwave needs to apply forces =
to neighboring objects as it expands but it should not be solid (i.e. =
objects could still exist within it's blast radius). =20
     Therefore the blast radius needs to be soft, providing forces but =
not so hard that it forces every object completely outside of its blast =
radius.
     Any tips from you pros on how to handle this properly?

Thank you for your help,
Jeremy Roberts
