Contact field output is requested for a node-based surface (*SURFACE, TYPE=NODE) spanning multiple instances in an Abaqus/Explicit analysis.
abaqus 中當(dāng)使用 硬接觸 功能中的 Allow separation after contact(不勾選)時(shí),出現(xiàn)下列警告,請(qǐng)教下要怎么解決At least one non-blank surface must be specified for contact surface interactions referencing NO SEPARATION surface behavior
Initial contact adjustments for resolving gaps and overclosures when a surface with double-sided facets is paired with any surface having double-sided facets may be incorrect.
THIS MAY BE DUE TO NONEXISTENT SLAVE OR MASTER SURFACE, OR DUE TO ERRORS WHEN PROCESSING THE *CONTACT PAIR KEYWORD我明明定義了slave surface 和 master surface。
邊界條件設(shè)置為:1)歐拉體頂端外沿V1=0(不發(fā)生外流) 2)歐拉體截面設(shè)置V2,VR1,VR3=0(對(duì)稱面) 3)歐拉體外側(cè)一圓弧包圍范圍內(nèi)設(shè)置了free inflow oulflow的設(shè)置,同時(shí)在load上對(duì)該位置施加pressure載荷 4)接觸設(shè)置為general contact,但是不包括四個(gè)surface-surface接觸,不包括的四個(gè)surface采用了surface
現(xiàn)在想設(shè)置材料在壓輥的滾軋作用和外界面熱源(激光)加熱作用下粘在一起,請(qǐng)問(wèn)如何設(shè)置?cohesive性質(zhì)用general contact和surface to surface(explicit)都報(bào)錯(cuò),surface base cohesive contact只能用于bonded contact?

forces are available only for the master side with node to surface contact types of interface # 4 input of data is completed initial kinetic energy = 0.14923890E+08 The LS-DYNA time step size should not

for the out-of-plane thickness of the corresponding surface under *surface interaction.
