Con­trolled self-mod­u­la­tion of long pro­ton or elec­tron beams is a new trend in plasma wake­field ac­cel­er­a­tion which sets a new goal for sim­u­la­tion codes. Long in­ter­ac­tion lengths (tens of me­ters), long beams (up to hun­dred of plasma wave pe­ri­ods), mo­tion of plasma ions, and vi­o­la­tion of fluid ap­prox­i­ma­tion are fac­tors that makes the prob­lem too heavy for gen­eral pur­pose codes. Only spe­cial­ized codes can at­tack this prob­lem in real geom­e­try. We de­scribe re­cent up­grades of the code LCODE which en­abled sim­u­la­tions of long dense pro­ton beams and re­port re­sults of nu­mer­i­cal stud­ies of pro­ton beam-plasma in­ter­ac­tion in the con­text of AWAKE pro­ject.
