# 7.3.1. Time-dependent tables for heat flux and heat transfer coefficient in sinkdef Similar as surfatab(2,j,i), sinkhftab(2,j,i) and sinkhtctab(2,j,i) can be used to define time-dependent tables for heat flux and heat transfer coefficient in sinkdef.
An example is provided below to demonstrate their usage. In the case of the first sinkdef(1:17,1) definition, if isinkhftab(1) > 0, it indicates the use of a time-dependent heat flux table for the first sinkdef(1:17,1). The symbol \* in isinkhftab(\*) should correspond to the # in sinkdef(1:17,#), which is 1 in this instance. Additionally, in sinkhftab(1:2,1:7,\*), the \* is associated with the # in sinkdef(16,1) = #, where \* and # are 3 here. Similarly, if isinkhtctab(1) > 0, it signifies the utilization of a time-dependent heat transfer coefficient table for the first sinkdef(1:17,1). The \* in isinkhtctab(\*) should match the # in sinkdef(1:17,#), which is 1 in this case. Moreover, in sinkhtctab(1:2,1:5,\*), the \* is linked to the # in sinkdef(17,1) = #, with \* and # being 2 here. The second sinkdef(1:17,2) is similar as the first one. In the case of the third sinkdef(1:17,3), if isinkhftab(3) = 0 (default), it indicates the use of a constant value given by sinkdef(16,3). Similarly, if isinkhtctab(3) = 0 (default), it signifies the use of a constant value given by sinkdef(17,3). {% hint style="info" %} $rheat … ihtflag = 1, sinkdef(1:17,1) = 1,2, 1,2, 1,2, 1, 7, 3.2632e+6, 0.01, 0.0, 390.0, 0.0,0,-1,3,2, isinkhftab(1) = 1, sinkhftab(1:2,1:7,3) = 0.0, -1.0e5, 500, 5.0e5, 1000, -8.0e5, 1500, 8.0e5, 2000, -5.0e5, 2500, 5.0e5, 3500, -5.0e5, isinkhtctab(1) = 1, sinkhtctab(1:2,1:5,2) = 0.0, 1.0e4, 100, 4.0e4, 300, 6.0e4, 1500, 10.0e4, 3000, 15.0e4, sinkdef(1:17,2) = 3,4, 3,4, 3,4, 1, 7, 3.2632e+6, 0.01, 0.0, 370.0, 0.0,0,-1,5,4, isinkhftab(2) = 1, sinkhftab(1:2,1:8,5) = 0.0, -1.0e5, 500, 1.0e6, 1000, -3.0e6, 1300, 9.0e6, 1500, 3.0e6, 2000, -1.0e6, 2500, 1.0e6, 3000, -1.0e6, isinkhtctab(2) = 1, sinkhtctab(1:2,1:6,4) = 0.0, 5.0e4, 500, 8.0e4, 750, 3.0e4, 1000, 10.0e4, 1500, 13.0e4, 3000, 23.0e4, sinkdef(1:17,3) = 2,3, 2, 3, 2,3, 1, 7, 3.2632e+6, 0.01, 0.0, 380.0, 0.0,0,-1, -1.0e5,8.0e4, isinkhftab(3) = 0, isinkhtctab(3) = 0, … $end {% endhint %} ## Input example {% file src="" %}
