Hello helper.,

Greetings..!

I am working on a compression analysis for Gyroid (a minimal surface lattice) with some hyperelastic material. The lattice block is a SOLID BODY with some thickness value (around 0.05 times unit cell length) which I'm trying to compress to very large deformation length (>65% of the block height). Initially I tried with Static Structural but I was unable to converge results.

This made me to consider Explicit Dynamics to go for... The solving Time issues are more here (Estimated is 20hrs) as I'm not sure how to set Analysis settings and time step values.

The compression rate is 5mm/min up-to 65% of block height, which is NOT an impact velocity.

Please help me to reduce solving time.

Hi

One can speed a quasi static analysis (which is what this is , so basically no dynamic effects) up, by ramping it up faster making sure the kinetic energy is less than the internal elastic one.
(So it is fast enough that we do not see any large dynamic effects on the response)
