Hello Friends,<\/p>\n
I’m analyzing the tube expansion process in ANSYS and running my model in EXPLICIT DYNAMICS; however, I get the “Time step too small” error.<\/p>\n
A few points to be added:<\/p>\n
1) The model was meshed with the same element size globally.<\/p>\n
2) Virtual Topology was applied. <\/p>\n
3) Mass scaling opted “yes” to reduce the analysis time.<\/p>\n
4) I tried to solve the issue by putting e-20 in the minimum time step cell, but still the model fails with the same time step error.<\/p>\n
5) You will see a history of this project in the General Mechanical channel at the link below. (Please note that the mesh has been modified for the purpose of running the model in Explicit Dynamics.)<\/p>\n

Please let me know what the reason might be for this error!<\/p>\n","protected":false},"template":"","class_list":["post-346909","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_oembed_60fc1da84a4dadd7dc5e87e3a57d2211":["
